Welcome to the Forums, Jimbcole. It will be hard for anyone to answer your question. The answers would depend on the condition of the unit, whether the systems are functioning, whether it is in towable condition, whether you intend to restore it, or if it has been restored.

With a rig of that age, it will be a challenge and a cash-sink unless everything goes perfectly all the time.

We look forward to learning more about you and the rig.

Pat
